4092A Operations and Maintenance Manual 3
1.3 4092A Overview
The TSC 4092A IRIG-B Autosense Fault Switch is a 1U (1.75") high, 19-inch, rack-mount,
autosense, fault switch that accepts two IRIG-B inputs and produces eight outputs (chosen from
the two inputs). The unit can be configured with redundant hot swappable AC or DC power
supplies. The TSC 4092A can also be configured to accept two 1-200 kHz sinewave signals but
traditionally would be used as an IRIG-B Fault Switch.
The front panel provides green/red LED status for the inputs and for all output signals, as well as
indicating the active input signal. A green/red LED on the front panel also provides power status.
The front panel also has a locking toggle control switch that you can use to manually switch
between input signals or to configure the unit to switch automatically upon input signal failure.
An Ethernet port on the rear panel provides the capability to remotely monitor the status of the
power supplies, input, and all output signals. Any failure in the unit will immediately provide an
alarm to this port.

For information about configuring the network connection, see “2.3 Assigning a Static
IP Address” on page 6.
2.3 Assigning a Static IP Address
The 4092A contains a Lantronix® Xport™ Ethernet to RS-232 converter, which provides the
4092A’s Ethernet connection.
The 4092A ships from the factory with a default IP address of 0.0.0.0, which enables DHCP. If the
network has a DHCP server, it will assign each unit an IP address, gateway address, and subnet
mask when the unit starts up.
4092A Operations and Maintenance Manual 7
To monitor multiple 4092A units remotely through their Ethernet connections, you must assign
each unit a fixed IP address. You identify which unit is the source of an alarm by its IP address.
Follow the instructions in this section to assign a unit’s IP address.
Note
For more detailed information, see the Xport User Manual. Section 3.3 discusses several different
ways that you can assign IP addresses. Chapter 4 explains how to permanently configure the IP
address. You can download the Xport User Manual from the Lantronix® Web site as an Adobe®
Acrobat® PDF file. Go to:
http://www.lantronix.com/
If you want to permanently configure the IP address, you must install the Lantronix
DeviceInstaller software. This software is available only by downloading from the Lantronix Web
site. Go to: http://www.lantronix.com
You can also assign the IP address using Telnet.
Note
If you move the 4092A to a different network hub after setting up the static IP address, the host
computer may not be able to make a connection. You may need to release the IP address lease on
your operating system.
To assign the static IP address using the Lantronix DeviceInstaller software:
1. Obtain the following network information from your system administrator for each 4092A
you want to install:
IP Address: ______ ______ ______ ______
Subnet Mask: ______ ______ ______ ______
Gateway: ______ ______ ______ ______
2. Connect a Windows® PC to the same local subnet as the 4092A.
3. Install and start the Lantronix® DeviceInstaller software.
4. Click the Search Network icon and search for XPORT devices connected to the network,
then click Save and Exit.
5. Click the IP icon or select Assign IP Address on the Tools menu.
The hardware device number and IP address appear in the Assign IP Address dialog
box.
6. Type the new IP address and click OK.
The new IP address appears in the Lantronix DeviceInstaller window.
7. Test the IP address by pinging the 4092A’s Xport on the Lantronix Xport Installer
window.
Click the Ping icon or select Ping Device on the Tools menu.
The Ping Device window should show the IP address of the 4092A’s Xport device,
and it should show successful replies if the IP address has been configured correctly.
8. Exit the browser.
8 2: Installing and Setting Up the 4092A
To assign the static IP address using Telnet:
1. Telnet to the assigned address, port 9999.
2. Press Enter within five seconds to enter the setup mode.
3. Select Option 0.
4. Set the IP address and follow the on-screen instructions to save the setting.
5. Telnet to the new IP address.

4092A Operations and Maintenance Manual 11
3: Monitoring the 4092A
3.1 Accessing the System
You access the 4092A system remotely by connecting to its Command-And-Response (CNR) Port
through the Ethernet connection. The CNR port (Port 10001), which uses TCP/IP, lets you input
commands, displays results of the commands, and publishes alarms as they occur.
When you Telnet to the CNR port, the system does not display a prompt.
3.2 Checking System Information
3.2.1 Checking Status and Alarms
The system can report status and alarms that occurred since the last status check.
To check system status:
Type: S
You do not need to type a carriage return or line feed.
The system returns Sabcde,fghij\r\n where
abcde is current status.
fghij is latched alarms and changed status since the last status request.
Both abcde and fghij are hexadecimal numbers, with each bit position representing one
output. LSB (farthest right) is output 1. MSB is the input. Bits 0–12 are latched alarms.
Bits 13–19 are change in status bits.
Latched alarms remain active in the current status field and latched status field until the
problem is corrected. Changed status bits are cleared upon next status request.
Example: S0A001,00001
This example shows that input B was selected using the front panel toggle switch, channel B is
active, and output 1 had a failure since the last status request.

the serial number of your unit ready to give to a technical representative.
4.1 Troubleshooting Input Problems
As long as the 4092A is in autoswitch mode and has two valid input signals connected, the unit
will automatically switch to the other input channel if it stops receiving a valid signal on the active
channel.
If the unit loses the active input signal, the LED for the that input turns red until you correct the
problem. To correct the problem, you must ensure that the channel is receiving a valid signal and
reset to the autoswitch mode.
Table 3 shows the INPUT LED states, their definitions, and actions required. Table 4 shows the
INPUT SELECT LED states, their definitions, and actions required.
Table 3: INPUT LED troubleshooting
Input LED status What it means What do to
One or both LEDs solid red The red LED shows that the channel is
not receiving a valid signal. 1. Check that the input cable is
connected.
2. Check that the input signal meets the
following specifications for
modulated signals:
• Signal type: IRIG-B
• Input level: > 2.8 V Peak to

3. Check that the input signal meets the
following specifications for
unmodulated signals:
• Signal Frequency: 1- 200 kHz
• Input level: > 1.5V Peak to Peak
into 50 Ω.
4. Check that the impedance and signal
type jumpers are set correctly. See
“4.4 Configuring for Input Signal
and Impedance” on page 19.
5. If the LED remains red, contact
TSC.
• See “5.1 Warranty Information”
on page 23.

4.4 Configuring for Input Signal and Impedance
The Input Signal and Impedance settings are configured at the factory for a modulated input and
low Z input and output impedance. If the signal sources have a high Z output impedance, then
Caution
When opening the top cover and changing the power supply settings, use proper ESD precautions.
This includes ensuring that you are properly grounded before touching the internal PWA of the
unit to change the jumper settings.
Required for this procedure:
#1 Phillips screwdriver
To change the jumper settings:
1. Disconnect both power supplies from their power source.
2. Using a #1 Phillips screwdriver, remove the top cover.
3. Move the jumper one position to the left to the 2S position.
4. Replace the top cover.
5. Reconnect the power supplies.
4.5 Configuring for Dual Power Supplies
The power supply setting is configured at the factory based upon single or dual power supply
configuration. If you are adding a second power supply to a unit that was originally configured for
a single power supply, you should change the internal jumper setting. The jumper setting ensures
that the power supply LEDs reflect the proper configuration and that the second power supply is
monitored.
Inputs A & B impedance jumpers
configured for the LO-Z (50 Ω).
Gain setting for selected input
impedance. Must follow Input
impedance.
Signal Type jumper configured for
modulated (IRIG-B).

5. Reconnect the power supplies.
4.6 Replacing Power Supplies
For units with a single power supply, the normal LED state is for one LED to be green and the
other not lit. For units with dual power supplies, the normal LED state is for both LEDs to be
green.
If a power supply LED is red, check that the affected power supply is connected to a properly
functioning 100–240 VAC, 50/60 Hz power source. If the LED remains red, you should replace
the power supply.
For AC power supplies, use only TSC 4501A power supplies. For DC power supplies, use only
TSC 4502A power supplies.
In a unit with dual power supplies, you can hot swap the power supplies. This means you can leave
the working power supply connected to power and all input and output devices connected when
you replace the failed power supply.
